' Referring tothe drawings, 1 represents the externally threaded neck ofa radiator which is provided with an inturned flange 2 form- 1 ing agasket-seat. 3 indicatesthe shell of the radiator. I

l My improved cap or closurecomprises a body member 4 internallythreaded to engage the neck and being locked in position thereby bymeans of a set screw 5, this set screw h'aving a head portion adaptedtobe broken off 7 afterthe body member ispositioned:

" VG- l v a with the groove, thelower wall of the groove The body memb ris Provided with a downi 'wardly facing shoulder 6 clamping the gasket Tarranged on the gasket seat 2. To effect I a more perfect sealing, theface of the shoulder 6 has annular grooves 8 therein. The body memberisalso provided with an I upwardly facing annularcha'nnel 9 in which Iarrange a gasket supporting ring 10 having a plurality ofspaced lingers11- whereby the gasket 12 is resiliently or yieldingly sup- ,v ported. IThe gasket itselfis preferably of yielding material although thusyieldingly f I supported, it may be of fibre, an-dat the same time aneffective seal is provided for the cover I 13 which has an annularjrib llcoacting with the gasket.

;, The cover 13 is pivotally connected to the body member, the pintle 15of the covered gaging av vertically elongated hole 16 in the pintleear17-see 2. This permits aL-m I limited vertical movement of the coverwhen 7 closed and resting or supported by the cover gasket, 12., A stop18 is provided on the ear I 17 to limit the openingswing of the cover. II The cover is locked in its closed position and clamped upon the cover.gasket by means of the locking ring- 19 rotatably mounted the outwardlyfacing groove 20 of theboidy member, the locking ring having a pluralityof inwardly projecting lugs 21 engaging inthisq so To permit engagementof these lugs hasaseries of slots 22 therein through which the lugs maybe passed. After thermg 1s in position with these lugs in engagement, astop :pin 23 is inserted through the groove tocoact :with one of thelugs. 1

,Thebody member is also provided with'a I pluralityofjrecesses Q l'adapted toreceive'the keepers 25 on' the cover, these keepers'having V slots"27' therein adapted'to "align with the groove 20 so that thelockingring may be en-' p i i Jgaged and disengaged with the" keepersbya rotative movement, "thereby clamping the cover downwardly jupon thegasket and locking it; V The locking ringhas inwai'dly facingfslot's 26which may be aligned withthe remisses-24:. The 'pivotfcon'nectionpermitting I theliinited vand verticalmovement,allows for .1 0 J r Ciladjustment of the cover so that it bears uniformly on the cover gasket.

The cover is quickly released or locked by a rotative movement of thelocking ring,at the same time it is very secure as an eiiective joint orseal.

I have illustrated my improvements in an adaptation to a projecting typeof radiator. However, it is well adapted for embodiment in the flattype. I have not .atteinpted toil.- lustrate such an adaptation hereinas'it is'believed that this disclosure will enable these skilled in theart to embody or adapt my improvements as may be desired.

Having thus described my invention, what 'I claim as new and desire tosecure by Letters Patent, is:

1. The combination of a body member, an upwardly facing annular gasketchannel, a spring supported annular gasket supporting member arranged insaid channel, a cover gasket supported by said gasket supportingmenroer, a cover having an annular rib on its under side coasting withsaid cover gasket, a pivotal connection for cover to said body memberpermitting vertical movement with the cover when closed, a plurality ofkeepers on said cover, and a locking member on said body adapted tocoact with all of said keepers.

2. In a structure of the class described, the combination or" a bodymember having an annular groove therein, a cover pivotally mounted onsaid body member having limited vertical movement when the cover'isclosed, a

spring supported gasket for said cover, a plurality of keepers on saidcover and a locking member rotatabiy mounted on said body membercoacting with all of said keepers.

3. In a structure of the class described, the combination of a bodymember provided with an upwardly facing gasket, a cover 'pivotallymounted on said body member for limited vertical movement when the coveris closed, a plusaid cap.

6. A radiator closure comprising an adapter having an openingtherethrough, a cap permanently and hingedly connected to said adapterand means for temporarily looking said cap against hinged movement, saidmeans including a projecting element on said cap having a groovetherein, a second projecting element rotatably mounted relative to theadapter {for extending into said groove and sockets formed in saidadapter for each of said projecting elements.

7. A radiator closure comprising a base having a slot therein, a .capconnected there- .to having a projection thereon adapted to be receivedin said slot and a rim mounted on said base capable of limited rotarymovement having means thereon 'for engaging said projection when in saidslot for preventing the withdrawal thereof.

8. A tan-k closure com-prising an adapter having an openingtherethrough, a rim carriedby sai d adapter and capable of limitedrotary movinnent relative thereto, a cap hinged to said adapter and lugscarried by said rim and projecting into said adapter,
